<a name="gtk3-Bindings.description"></a><h2>Description</h2>
<p>
<a class="link" href="gtk3-Bindings.html#GtkBindingSet" title="struct GtkBindingSet"><span class="type">GtkBindingSet</span></a> provides a mechanism for configuring GTK+ key bindings
through CSS files. This eases key binding adjustments for application
developers as well as users and provides GTK+ users or administrators
with high key  binding configurability which requires no application
or toolkit side changes.
</p>
<p>
</p>
<div class="refsect2">
<a name="gtk-bindings-install"></a><h3>Installing a key binding</h3>
<p>
A CSS file binding consists of a 'binding-set' definition and a match
statement to apply the binding set to specific widget types. Details
on the matching mechanism are described under
<a class="link" href="gtk3-GtkCssProvider.html#gtkcssprovider-selectors" title="Selectors">Selectors</a>
in the <a class="link" href="gtk3-GtkCssProvider.html#GtkCssProvider" title="struct GtkCssProvider"><span class="type">GtkCssProvider</span></a> documentation. Inside the binding set definition,
key combinations are bound to one or more specific signal emissions on
the target widget. Key combinations are strings consisting of an optional
<a href="../gdk3/gdk3-Windows.html#GdkModifierType"><span class="type">GdkModifierType</span></a> name and key names
such as those defined in <code class="filename">&lt;gdk/gdkkeysyms.h&gt;</code>
or returned from <a href="../gdk3/gdk3-Keyboard-Handling.html#gdk-keyval-name"><code class="function">gdk_keyval_name()</code></a>, they have to be parsable by
<a class="link" href="gtk3-Keyboard-Accelerators.html#gtk-accelerator-parse" title="gtk_accelerator_parse ()"><code class="function">gtk_accelerator_parse()</code></a>. Specifications of signal emissions consist
of a string identifying the signal name, and a list of signal specific
arguments in parenthesis.
</p>
<p>
For example for binding Control and the left or right cursor keys
of a <a class="link" href="gtk3-GtkEntry.html#GtkEntry" title="struct GtkEntry"><span class="type">GtkEntry</span></a> widget to the <span class="type">"move-cursor"</span> signal (so movement
occurs in 3-character steps), the following binding can be used:
</p>
<div class="informalexample"><pre class="programlisting">
@binding-set MoveCursor3
{
  bind "&lt;Control&gt;Right" { "move-cursor" (visual-positions, 3, 0) };
  bind "&lt;Control&gt;Left" { "move-cursor" (visual-positions, -3, 0) };
};
GtkEntry
{
  gtk-key-bindings: MoveCursor3
}
</pre></div>
<p>
</p>
</div>
<p>
</p>
<hr>
<div class="refsect2">
<a name="gtk-bindings-unbind"></a><h3>Unbinding existing key bindings</h3>
<p>
GTK+ already defines a number of useful bindings for the widgets
it provides. Because custom bindings set up in CSS files take
precedence over the default bindings shipped with GTK+, overriding
existing bindings as demonstrated in
<a class="link" href="gtk3-Bindings.html#gtk-bindings-install" title="Installing a key binding">Installing a key binding</a>
works as expected. The same mechanism can not be used to "unbind"
existing bindings, however.
</p>
<div class="informalexample"><pre class="programlisting">
@binding-set MoveCursor3
{
  bind "&lt;Control&gt;Right" {  };
  bind "&lt;Control&gt;Left" {  };
};
GtkEntry
{
  gtk-key-bindings: MoveCursor3
}
</pre></div>
<p>
The above example will not have the desired effect of causing
"&lt;Control&gt;Right" and "&lt;Control&gt;Left" key presses to
be ignored by GTK+. Instead, it just causes any existing bindings
from the bindings set "MoveCursor3" to be deleted, so when
"&lt;Control&gt;Right" or "&lt;Control&gt;Left" are pressed, no
binding for these keys is found in binding set "MoveCursor3".
GTK+ will thus continue to search for matching key bindings, and will
eventually lookup and find the default GTK+ bindings for entries which
implement word movement. To keep GTK+ from activating its default
bindings, the "unbind" keyword can be used like this:
</p>
<div class="informalexample"><pre class="programlisting">
@binding-set MoveCursor3
{
  unbind "&lt;Control&gt;Right";
  unbind "&lt;Control&gt;Left";
};
GtkEntry
{
  gtk-key-bindings: MoveCursor3
}
</pre></div>
<p>
Now, GTK+ will find a match when looking up "&lt;Control&gt;Right"
and "&lt;Control&gt;Left" key presses before it resorts to its default
bindings, and the match instructs it to abort ("unbind") the search,
so the key presses are not consumed by this widget. As usual, further
processing of the key presses, e.g. by an entry's parent widget, is
now possible.

<p>
A binding set maintains a list of activatable key bindings.
A single binding set can match multiple types of widgets.
Similar to style contexts, can be matched by any information contained
in a widgets <a class="link" href="gtk3-GtkWidgetPath.html#GtkWidgetPath" title="GtkWidgetPath"><span class="type">GtkWidgetPath</span></a>. When a binding within a set is matched upon
activation, an action signal is emitted on the target widget to carry out
the actual activation.
